It has been common as a given name in the English-speaking world only since the 18th century. A famous modern bearer is American actress Julia Roberts (1967-).
This is not the usual spelling in any of the Scandinavian languages (in Sweden and Denmark it is Freja and in Norway it is Frøja) but it is the common spelling of the goddess's name in English. In the 2000s it became popular in Britain.
In England, this Latin form has been used alongside the vernacular forms Ann and Anne since the late Middle Ages. Anna is currently the most common of these spellings in all English-speaking countries (since the 1970s), however the biblical form Hannah is presently more popular than all three.
The name was borne by several Russian royals, including an 18th-century empress of Russia. It is also the name of the main character in Leo Tolstoy's novel Anna Karenina (1877), about a married aristocrat who begins an ultimately tragic relationship with Count Vronsky.
